About singulair-montelukast

General Info: Uses and Effects

Singulair is a selective, oral leukotriene receptor antagonist that specifically inhibits cysteinyl leukotriene CysLT1 receptor. This leads to blockage of the leukotriene effect and reduced bronchi sensitivity to allergens.

Singulair is useful as an additional drug in preventing and permanently treating asthma, especially in those patients in whom corticosteroids and other bronchodilators cannot fully control asthma symptoms. Montelukast is particularly useful in patients who suffer from so-called allergic asthma, as well as in the prevention of asthma attacks resulting from physical efforts. The drug can also be used to prevent seasonal allergic rhinitis.

As Singulair is a relatively new drug, the risk of its using in pregnancy and breastfeeding is not fully determined, but caution is advised when used in this population. During clinical trials it was established that Montelukast is well-tolerated and rarely causes severe adverse effects.

Contraindications: Important to Know

The only known absolute contraindication to the use of Singulair is hypersensitivity (allergy) to its active substance Montelukast. If you are not sure whether you are allergic to it, please consult your doctor.

Most common symptoms of an allergic reaction include swelling of the lips, swelling of the throat, difficulty breathing and anaphylactic shock. If you notice any symptoms of an allergic reaction, you must call your physician immediately.

Rare cases of systemic eosinophilia have been reported. Systemic eosinophilia is characterized with severely decreased number of leukocytes in the blood which will significantly impair the ability of your immune system to fight against infections. Therefore, even weak bacteria or mild infection may cause severe complications and may be fatal in certain circumstances. Therefore, you must inform your doctor at once if you notice any flu-like symptoms.

Rare cases of cardiovascular toxicity induced by Singulair have also been reported. If you notice palpitations, chest pain, rapid heartbeat or hypertension, you should inform your doctor. In these cases, your physician may decide to switch you to other drug.

There are no sufficient clinical data to confirm its efficacy and safety in pregnant and breastfeeding women. Therefore, you should always consult your doctor about Montelukast use during pregnancy or breastfeeding.

Dosage

The recommended dosage for adults aged 15 years or older, who suffer from asthma, or seasonal allergic rhinitis, is one tablet of Singulair (10mg) daily, taken in the evening.

The therapeutic effect of Montelukast usually occurs after only one day. Singulair can be taken with or without food, because food has insignificant effects on its absorption.

Patients should be advised to continue taking Singulair even when their asthma symptoms are under control. The drug should not be used concomitantly with other medicinal products that have the same active ingredient called Montelukast.

It is not necessary to adjust the dose neither in elderly patients, nor in patients with renal insufficiency or mild to moderate hepatic insufficiency. There are no data whether this drug is sage to be administered in patients with severe liver failure. The dose is not different in male and female patients.

Singulair can be used as an additional therapy to an already existing patient treatment protocol. It can be used as an additional therapy when inhaled corticosteroids and short-acting beta-agonists do not provide adequate control of asthma. Montelukast should not be rapidly introduced as a replacement for inhaled corticosteroids.

It also exists in the form of chewable tablets (5mg) that are intended for pediatric patients aged 6 to 14 years.

Side Effects

Singulair Montelukast may cause following side effects:

Infections of the upper respiratory tract (affects more than 1% of patients);

Bleeding disorders (affects less than 0.01% of patients);

Allergic reactions including rash, swelling of the lips, swelling of the tongue and/or throat and difficulty breathing (affects less than 0.01% of patients);

Apalutamide - a drug used to treat non-metastatic prostate carcinoma. It may decrease the plasma levels of Singulair making it less effective in asthma treatment.

Somatropin - a growth hormone used to treat growth failure in children. The medicine reduces blood levels of Singulair making it less effective.

Zafirlukast (Accolate) - a drug used to prevent asthma. The concomitant use increases risk of side effects, such as bad dreams, depression, suicidal ideas, fever, headache, hallucinations, sleepwalking, and tremor.

Worst service

Starting for the delivery guy, to the phone operators, you would think they were giving you for free, and I am the one ordering the drug, and paying! Really, this is not the only medication that I can use in the world. Worst service ever!

Sinuses managed

I used it on my son’s sinuses, couldn’t believe the fevers and the headaches. Wish there was something they could do about it. Anyhow, at list the sinus is managed with Singulair medicine.

Excellent drug

Fair

Well, I wish they could do something with the singulair 10 taste, it leaves a bitter taste on your tongue. It’s really difficult to swallow especially if you’re chewing. Anyway it’s not too bad, I guess it’s fair.

Substandard medication

Wanted to try Singulair generic for my allergies. Turns out, it’s not as effective as they say it is. This drug is so substandard! Best in town my foot!
